Wuala is a cloud backup and sync application designed to help users securely store, share, and access their data across multiple devices. It provides a secure and private platform to store files, photos, videos, documents, and other digital content, and allows users to sync files between their computers, smartphones, and tablets. It is cloud-based, meaning that it can be accessed from any device with an internet connection. It also provides an easy way to share files with friends and family. The data is encrypted using AES-256 encryption and stored on multiple secure servers located in different countries. It also supports two-factor authentication for added security. Wuala was acquired by LaCie in 2013 and is now part of their family of cloud storage solutions.
